how do i configure this keyboard for raspberry pi mapping?

There is no custom mapping required for the raspberry pi. My pi has been running RASPBIAN with the keyboard set to default just fine. If you want to setup any custom mapping, try looking at the assorted linux forums for custom mapping within whichever distro you are intending on using.

Is it a mechanical keyboard?

Search out "Mechanical Keyboards: Should You Switch?" on the web. Lots of good info there.
